In a 2000-line interpreter I used:
- FiniteMap (for environments),
- Dynamic & Exception (for exceptions in the language being implemented
  and compile errors),
- MonadReader, MonadError (for convenience, in two places),
- MVar (could be IORef; for mutable objects in the language being
  interpreted),
- unsafePerformIO (for three global variables: unique supply,
  loaded modules, search paths),
- Readline (for the interactive toplevel).
